Build linux pg graphql

[charlesBochet]

Context

As we have patched pg_graphql in #3204, we can no longer rely on pg_graphql prebuild image for our docker container.
We have already learned how to build it for macos intel and arm so it is not a big deal

What

1. In this PR, I'm adding a script to build pg_graphql on linux. As most of the core team is running on MacOS, I've been forced to execute this script in a linux container.
2. I have used this script to build pg_graphql extension files (.so, .control, .sql) for AMD and ARM and added them to the repository
3. I have updated our production Dockerfile to use these files instead of pulling pre-built files
